Featuring an upgraded 11 mm sensor head tip, this 3300 XL series probe provides a wider linear measurement field than standard 8 mm variants, making it ideal for tracking large thermal growth variations and axial thrust drift in utility-scale steam turbines, industrial gas expanders, and heavy-duty gearboxes. The internal coil structure feeds dynamic voltage shifts directly into Bently Nevada 3500 rack architectures or multi-tier Distributed Control Systems (DCS). Operating as a rugged input transmitter inside safety-critical Emergency Shutdown (ESD) control loops, this probe tracks large-scale displacement trends and instantaneous vibration over-travel, enabling engineering teams to prevent catastrophic rotor-to-stator contact.\u003c\/p\u003e\n\u003ch2\u003eMechanical Option Architecture\u003c\/h2\u003e\n\u003cp\u003eBently Nevada uses an exact

Instructions\u003c\/h2\u003e\n\u003cp\u003eAchieving accurate calibration curves relies on precise physical depth setting during field commissioning. Field engineers must monitor the raw DC gap voltage across the Proximitor Sensor output terminals using a high-impedance digital multimeter while positioning the sensor. Thread the 1\/2-20 UNF probe body into the mounting bracket until the multimeter registers exactly -10.0 VDC, which confirms that the target shaft face sits precisely in the middle of the 11 mm probe's extended 4.0 mm linear calibration zone.\u003c\/p\u003e\n\u003cp\u003eObserve rigid routing constraints to ensure continuous signal integrity across the loop. The flexible stainless steel armor conduit demands a minimum mechanical bend radius of 25.4 mm (1.0 inch) to prevent internal coaxial kinking and avoid signal impedance drops. Field teams must contain all miniature coaxial connector joints inside a dedicated, weatherproof local junction box to eliminate lubrication oil or moisture entry. Electrically isolate the probe body from local structural machine ground, terminating the shield drain wire solely at the 3500 monitoring rack chassis ground terminal strip.\u003c\/p\u003e\n\u003ch2\u003eCritical Infrastructure Integration\u003c\/h2\u003e\n\u003cp\u003eThis extended-range proximity sensor withstands the punishing conditions of heavy industrial processing, including extreme thermal cycling, heavy casing vibration, and continuous oil submersion inside turbine housings. It integrates natively into comprehensive Turbine Supervisory Instrumentation (TSI) upgrades. The low-attenuation core delivers flawless analog signal waveforms over its entire run, interfacing smoothly with modern process control engines like Honeywell Experion PKS or Siemens S7 PLC architectures to ensure predictive diagnostic tools receive error-free dynamic waveform data.\u003c\/p\u003e\n\u003ch2\u003eOrdering and Content Information\u003c\/h2\u003e\n\u003cp\u003eEvery ordered procurement kit includes the essential hardware components required for rapid field deployment.

This extended range allows the sensor to monitor large axial displacements and thermal expansion trends without going out of limits.\u003c\/p\u003e\n\u003ch3\u003eQ2: What does the -12 configuration suffix define on this model string?\u003c\/h3\u003e\n\u003cp\u003eA2: The -12 suffix indicates that the integrated coaxial cable includes a flexible stainless steel armor jacket combined with a built-in connector protector. This design shields the cable from mechanical damage and locks the terminal link against fluid contamination.\u003c\/p\u003e\n\u003ch3\u003eQ3: What is the calibrated voltage scale factor for this 11 mm transducer loop?\u003c\/h3\u003e\n\u003cp\u003eA3: This 3300 XL 11 mm system generates a nominal scale factor of 3.94 V\/mm (100 mV\/mil). This differs from the standard 8 mm probe scale factor of 7.87 V\/mm (200 mV\/mil) because it stretches the measurement profile across a wider physical gap span.\u003c\/p\u003e\n\u003ch3\u003eQ4: Can I pair this 1.0-meter probe cable with a standard 3300 XL 8 mm Proximitor Sensor?\u003c\/h3\u003e\n\u003cp\u003eA4: No, you cannot mix these loops. This 11 mm probe requires a dedicated 3300 XL 11 mm Proximitor Sensor calibrated for 100 mV\/mil operation. Connecting it to an 8 mm Proximitor Sensor will destroy loop calibration and cause incorrect measurement outputs.\u003c\/p\u003e\n\u003ch3\u003eQ5: How do I arrange commercial payment to ensure immediate order processing?\u003c\/h3\u003e\n\u003cp\u003eA5: We accept verified commercial telegraphic wire transfers (T\/T), standard proforma corporate invoicing, and major verified credit accounts to accelerate the financial clearance phase and initiate priority packaging routing.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518870773933,"sku":"330709-00-05-10-12-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330709-00-05-10-12-05-3300-xl-11-mm-proximity-probes-0hfzc4lla2k.jpg?v=1766980670","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330709-00-05-10-12-05-3300-xl-11-mm-proximity-probes","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
